Abstract
Description
-
- a) DICOM compatibility problems during network communication between DICOM nodes, both forwards, backwards and with products from other producers, must be generically resolved as well as in the context of specific architecture configurations.
- New systems must take into account how old systems (legacy systems) or other products behave. Therefore, expensive “patches” and much test expenditure are needed.
- b) Maintaining anonymity of patient data and other security-relevant requirements, must be solved for specific configurations without changes in the existing DICOM products.
- The anonymity protection must be incorporated by fixed coding into the products today.
- c) “DICOM Messages” from and to purchased simulators and test instruments can not be customized so as to be specific to the customer at runtime (on the fly), for example an HIS/RIS simulator can fill DICOM fields with zeros, but cannot forward empty fields, however old systems send unknown fields as empty fields.
- This is only remedied by the development of expanded simulator instruments, or special versions for test instruments.
- a) DICOM compatibility problems during network communication between DICOM nodes, both forwards, backwards and with products from other producers, must be generically resolved as well as in the context of specific architecture configurations.
-
- Transparent proxy between an older generation of DICOM-based products and a new product.
- Transparent proxy between DICOM products of various producers or interpretations.
- Security firewall to other networks or DICOM nodes.
- Expansion of DICOM simulators or interoperability test instruments.
